WASHINGTON (AP) — President Donald Trump is ordering a massive overhaul of the National Security Council that will shrink its size and return many career appointees back to their home agencies, according to two U.S. officials and one person familiar with the reorganization.

The dismissals, part of plan to radically downsize the National Security Council, follow President Donald Trump’s recent ouster of his national security adviser.

WASHINGTON (Reuters) -A large restructuring of the White House National Security Council got under way on Friday as President Donald Trump moved to reduce the size and scope of the once-powerful agency, five sources briefed on the matter said.
